       Amendment 1 to Form S-1 Filed on March 3, 2022

       Capitalization, page 21

   1.                                                   Please clearly disclose
how you are arriving at each pro forma amount in the notes to your
                                                        capitalization table,
including any significant estimates and/or assumptions used to
                                                        determine such amounts.
Your current disclosure is not descriptive enough to enable
                                                        investors to calculate
the amounts you present.

   2.                                                   You disclose on page 29
that you paid $196,887 in cash for interest during the year ended
                                                        December 31, 2020;
however, the related amount per page F-8 is $99,065. Please revise
                                                        your disclosure to
address this apparent discrepancy.
